I have this pluign installed on several sites and it works well on all but one. In the one site where it doesn’t work, I activated it and then tried to go to http://accessible-techcomm.org/sitemap.xml to build the first one. The problem is that the link gets changed somehow to
http://accessible-techcomm.org/sitemap.xml/ and is routed to the home page. So nothing is generated and put in /wp-content/sitemaps. That folder sits empty.

I’ve tried adding this to the htaccess file:
Redirect 301 /sitemap.xml/ http://accessible-techcomm.org/sitemap.xml
but I am now thinking that may result in an endless loop.

How do I get this to work?
